We have long supplied CHIMEI, LG, and INEOS acrylonitrile-butadiene-styrene materials. However, these ABS materials are gradually losing their competitive edge in China's price wars. We hope to find more cost-competitive ABS materials to preserve our profit margins.

But in my discussions with Jonathan from OS3DP, he came across 750SW while trying to find a polymer which behaves as close to MG94 as possible....this was because of the MG94 global shortage from recent months. While MG94 is back in stock, I still wanted to play around with this to weigh options, see how it handled, and just have fun making filament!

Side by side, MG94 and 750SW pellets look nearly identical. The only thing setting them apart is that the 750SW is closer to a white instead of a neutral tone like virgin MG94.

Printer:
Solidoodle 2, E3D Titan, E3D v6, E3D Volcano, Sanguinololu, Supernight PSU, Lawsy carriages, mirror bed+Auqua Net Super Hold, bed stabilizer, fishing line, pillow block

Printing:
The 750SW printed identical to MG94, so it was very smooth, retained its almost-white coloration, and didn't appear to have as strong of fumes as some other polymers, less even than MG94 which is already pretty low.

And yes, I printed a fidget spinner. :rolls eyes:

Comparison to available filament:
750SW is a tough contender for MG94, so I would call it a draw between the two. It prints very smooth but seems to take a touch longer to cool than other ABS variants. I noticed this while pulling the filament out of the extruder (direct feed Titan) and it snagged on the PTFE guide coming out. Maybe a slightly lower temp would help for prolonged use, and a nozzle fan would really help for smaller parts.

Takeaway and comments:
I am very happy with my investment! It is about $3 cheaper per 1kg than MG94, is very similar, and is less brittle. I attempted to bend and snap the first of the roll to load a consistent diameter into the Titan and ot would not snap! It does seem to be a little more durable than MG94 or PA747 like I am used to using, and it has a texture I can't really explain. It doesn't have a slick grip like TPU, it's not slick like MG94, nor is it a dry grip like PA747. It really does sit in a league of its own, but it really is similar, once again, to MG94. If you like said polymer, I recommend trying 750SW as it can be indistinguishable and cheaper at the moment.
